John Frankenheimer could do little wrong in the early 1960's and this political thriller, an adpatation of Richard Condon's novel, stands as probably his finest achievement. The film is dazzlingly photographed (in B&W), memorably performed (by Angela Lansbury in particular) and is blessed with a bitingly, satirical script containing surprise, humour, pathos and moments of shocking violence. There are some flaws: the plot is preposterous and Laurence Harvey makes no attempt at an American accent; but the film is so gripping from the outset that these are easily overlooked. On the DVD, the film is presented in its original widescreen format with mono sound. Picture and audio quality are both adequate. The main extras are a commentary track from John Frankenheimer and short retrospective interviews with Frankenheimer, Frank Sinatra and screenwriter George Axelrod. Unfortunately, neither are particularly illuminating.
